Attractive springs
Instead of using electricity or pressed air, MagSpring magnetic springs use permanent magnets and iron to deliver a constant force for assisting and resisting loads. Magnets are located inside the slider, stator, or both. Beneficial in vertical as well as horizontal applications, MagSprings compensate for payload weight, giving smaller motors greater range. During power losses, they can raise, hold, or more slowly lower a payload.
